TNHO Lock Hex Nuts for Industrial Fastening
Our hex nut series includes standard hex nuts, thin nuts, staked lock nuts and nylon insert lock nuts. Made of...
Our hex standoff series includes male-female spacer studs and full female coupling nuts in brass & zinc-plated steel, standard specs M3×51, M4×25 with customizable lengths. These precision spacers are specially designed for electric meter PCB isolation, component spacing and internal frame assembly. Male-female thread structure enables stacked connection, excellent conductivity from brass material and anti-rust coating from zinc plating, perfectly satisfying insulation, spacing and fixed mounting demands of power metering equipment internal electronic modules.

1.Two mature structural types for flexible assembly: Male-female standoff and double female coupling nut realize single fixation or multi-section stacked splicing to adjust PCB spacing freely.
2.Two optional functional raw material selections: High-conductive brass for circuit conduction and zinc-plated steel for economical general isolation mounting scenarios.
3.Precision tapped uniform internal & external thread: Fine tapping craft ensures smooth thread matching to prevent sliding thread and loose after long-term equipment vibration.
4.Hexagonal outer anti-rotation body design: Six-flat hex profile makes wrench clamping convenient and effectively avoids spacer spinning during tightening operation.
5.Wide customizable dimensional range for diverse needs: Besides standard M3/M4 specs, we tailor thread diameter and full length to match unique meter internal structural layout.
Optimal isolation & spacing performance for meter PCB
Effectively separate circuit board from metal/plastic shell to avoid short-circuit caused by contact and improve meter operation safety.
Excellent material property matching different working conditions
Brass resists oxidation to keep stable conductivity; zinc coating protects steel spacer from rust in damp meter cabinet inner environment.
Flexible stacked combination to save accessory inventory
Free splicing of standoff and coupling nut reduces various spare spacer specs and cuts customers’ stocking cost.
Strict CNC machining to guarantee dimensional consistency
Precision lathe processing controls tolerance steadily to raise assembly efficiency of automated meter PCB production line.
Spot stock for regular M3/M4 mainstream specifications
Ready inventory for common sizes enables fast sample delivery and quick response to clients’ urgent bulk order demand.
Full customization service adapting global meter design
Modify shape, length and material strictly following overseas customers’ electric meter development drawings and prototype samples.
